Membrane Fouling and Mitigation Strategies in PVDF-Based MBRs
Membrane fouling poses a significant challenge for the performance and longevity of polymeric membrane bioreactors (MBRs). Particularly, polyvinylidene fluoride (PVDF)-based MBRs are susceptible to multifaceted fouling mechanisms, comprising deposition of extracellular polymeric substances (EPS), microbial attachment, and particulate matter accumulation.
These deposition events can drastically diminish the permeate flux, increase energy consumption, and ultimately compromise the efficiency of the MBR system.
Numerous strategies have been proposed to mitigate membrane fouling in PVDF-based MBRs. These strategies can be broadly categorized into preemptive and reactive approaches. Preventive measures aim to reduce the formation of foulants on the membrane surface by optimizing operational parameters such as transmembrane pressure (TMP), hydraulic retention time (HRT), and feed water quality.
Corrective methods, on the other hand, focus on eliminating existing fouling layers from the membrane surface through physical or chemical procedures. Physical cleaning methods encompass backwashing, air scouring, and manual removal, while chemical cleaning employs agents such as acids, bases, or enzymes to dissolve or degrade fouling materials.
The choice of mitigation strategy depends on the specific fouling mechanisms existing in the MBR system and the operational constraints.
